Hi, im trying to paste over and over again the noise of a fan on cool edit pro. But there's no way to make the soundtrack continuous, and there's always a drop in volume at the end of each part I have recorded. How can i make it so the recording is continuous and there's no drop in volume? THANKS! :-/

Jul 28, 2010 01:50 pm Well I first managed to get the fan down to same volume by using hard limiting. Now I've encountered this problem, which i also had on expstudio audio, and i guess is everywhere. In principle it seems so simple, but I haven't a clue how to solve it. Apparently the beginning and end of every wave we select takes in a steep drop in volume at the end start and the end, for no reason whatsoever.
On cool edit pro, bouncing i think is selecting waves, am i right? anyway, i selected the wave, copied it a few times, and normalized it, which i guess should in theory put it all back at the same volume, but the result was disastrous again.
Surely there's gotta be a way to eliminate this problem at the root, and abandon these waves that seem to unreasonably drop steeply at the start and the end.
I'd greatly appreciate any help on this.
Jul 28, 2010 01:52 pm plz could a moderater change the title of my thread to something like 'Volume problem attempt at equalizing''?? thx
Jul 28, 2010 07:39 pm Why does it get quiet at the end? If a mic is sitting in front of a source and that source is producing noise before and after you hit record then there should be no change.
Anyway, I would just snip off the end (and beginning if needed) of where it starts to get quiet and then loop the parts that are uniform.
Jul 28, 2010 07:54 pm yeah tis what i was thinking Cap. Or maybe a delay just coming on at the end and the off again before it starts again, using a short time, just to smooth it over.
Jul 28, 2010 09:05 pm i guess cool edit doesnt do this, but most newer audio editors will allow for u to do a volume envelope (automation), basically u can program in a person turning up the volume on teh part, so if u program it inversely to how it fades out.... should make it equal?
Jul 29, 2010 02:16 am cpttripps, just to show u how irritating and inexplicable this problem is to me, i have a bunch of waves in front of me, on cool edit pro, that represent the sound of the box fan. So i do what u or i would think would work with no problem, i cut the wave chops into smaller and smaller pieces, but with every cut there comes and end part where the audio goes down, and that's recorded and i'm stuck with it every time i try to copy something new, i.e. another bit of fan, onto the track. inexplicably by default both cool edit pro and exp audio studio have a weird ending sound at the end of each wave, no matter how perfect you thought that wave was, and is on the previous bit of soundtrack.
its not a mic, but a downloaded longer bit of box fan from the internet. im trying to loop it but there's just no way!!!
automation sounds a step in the right direction, but doesnt seem to cure the ill at the root, since the inverse a volume drop would probably also be irregular, if not a spike. but i'd like to try it, i guess. what newer audio editor would u recommend, crux?
im kinda blown away, thou, after all arent these sound waves on the audio editors just that, sound waves. why do both audio editors ive tried have volume problems by default at the end of every cut, it sounds absurd.
again, im desperate for help, thanks.
Jul 29, 2010 03:19 am to be honest onething im not 100% on ur situation, but i dont think using an inverse envelope would cause a spike, as long as the end of the envelope is equal to the beginning of the fade out
i use Cubase SX3, but im sure even the free ones like Reaper would do the trick
Jul 29, 2010 12:09 pm Hmmm, that is strange as can be.
How about you send me a link to the file, or the file itself and I will create you a long *** file of fan noise. I don't know what the problem could be but I figure if you had 5 minutes of it looped that should be enough aye?
Jul 29, 2010 03:12 pm thanks tripps, first ill dld cubase and see if inverse envelope works. if not ill come back to u.
crux, im not sure this weird fade out ends in zero, i hope so, ill try cubase or reaper
the automations or envelopes on cool edit thou dont have the inverse envelope option as a preset
Jul 29, 2010 04:03 pm hey, i'd be interested to see the file as well if you want to post a link...
Jul 29, 2010 09:45 pm not to be a broken record but i dont think the inverse envelope has to end at 0, and i dont know if cool edit restricts u to using only a preset?
I was takling more about just earing it, basically moving ur automated fade as u listen in a way that sounds natural and does away with the fade out, no need to get set numbers on it.
Aug 01, 2010 12:03 am Hey there,
well after two days of epic fails, im back and ready to grumble
ok where do i start
When it's probably very simple; i shrink table after table of these audiological terms. Cubase's instructions only mentioned envelopes once in their manual, and even then I couldn't make head or tail of it. There was no mention of inverse enveloping. There were some mentions of automation, but im at a loss. When I tried to select the envelopes at Cubase, I got even farer from making any sense of it; i apparently had to make a few links from point to point.
With Reaper, directly when I went to the envelope section, anything that promised anything like 'linear set shape for all selected points' or 'invert selected points' were all greyed out and unclickable.
Right now, I'm basically stuck in two problems, as illustrated in this screenshot:
On the left is my attempt in cool edit pro. I got these 7 seconds of box fan from a 10 second box fan clip where there really is fade in and out. This is supposed to be the centre where everything is OK. However, I've highlighted in red these failings the hard limiting I exposed the sound to had, making it irregular and far from the constant sound I need to sleep with. If there was any way to get rid of these gaping white spaces at the top and the bottom of the waves, I'd greatly appreciate a solution. However my main problem right now is looping, as illustrated on the right of the screenshot.
On the right is my attempt with Cubase 5, and its merely the same problem I had at Cool edit pro. The red circles here indicate the big jumps or sinkages in volume i had when i tried to repeat the tracks.
Just like in cool edit pro, and this is because I'm at a loss as to how to start enveloping, automating and inverse enveloping. Again, this is due to a lot invompetence on my part. My feeling is these instructions are huge and there's something i'm missing, even thou the solution is probably very simple (greyed out options... being unable to find inverse enveloping etc)
Here is the sound of the 7 seconds of box fan that in theory shouldn't fade out, but do perhaps because mp3s are designed that way, in an instant fade.

And here's the jump at 7 secs when i try to repeat the track on any sound edit software:

anyway, thanks for your time and patience, if u do tackle this. I will tomorrow, again, cuz today im frustrated :-)
Aug 01, 2010 09:55 am Im sorry but i dont hear any fade out at all... but i would imagine simply cutting and paste this sound would be very troublesome. Even though the sound seems repetitive and random these things always make it very obvious that they are looping and where the loop begins and ends... in Cubase u can "time stretch" audio, to make it long, it will make the clicks and pops and things also longer so it might sound unnatural but u never know
on "inverse enveloping"yes Cubase calls it automation in terms of teh function. U "automate" to create "envelopes". But u dont need to find a button to do an inverse envelope. If u can automate as i said before u can just 'ear" it. set ur two points where u hear the fade begin and end and just drag the ending point up in volume and listen back until u feel like the volume is moving "inversely" to how the sound is fading. Its really not a preset or computer help situation, in real life it would be like u physically turning the volume knob up as the sound faded away so that to the listener it wouldnt sound like a fade out at all.
another fix that Cubase offers for repeating a loop that doesnt go well together, is Crossfading. It should be pretty simple but i havent done it in years so check the Help, but basically u overlap the loops u want, hit crossfade and the computer fades one out as the other fades in and u can adjust it so that it happens almost instantly, should make it pretty clean.
goodlux
Aug 01, 2010 11:43 am thanks, ill get to work on ur suggestions
However, as u said, there's no fade out. Thou i didnt make it clear, my problem is a cut at the end of each repeat, which you can see on the 7-8th second of the second mp3. Right now this is my main technical difficulty how to add sounds without there being a cut. Once i get past this ill get to the other issues. Crossfading sounds v interesting for them.
The problem with these cuts is they seem to be ingrained in mp3 architecture. Ill try automation and tell u how it went this evening, cheers
Aug 01, 2010 09:00 pm yeah it sounds like crossfading should help as u dont have to connect the loops at their cut points, they will connect somewhere in the middle.
a brain fart i had while typing that was u could actually loop the sound on different tracks without connecting them, that way one could start just a fraction of a second before the other one ends. Coupled with some fading (basically manual crossfading)when u mix down the two tracks it would create the illusion of one continuous sound.
Aug 02, 2010 01:16 am Ok, so I'm pretty sure I know what the problem is. I will take this to Audition and play with it for a second, but I'm pretty sure your problem is that the sample ends at some point not on the 0 line. The end of a sample should always be cut where the wav crosses the zero (0) line. If not you will get a little pop. This is what I believe is happening in this sample, but I'll check for sure in a moment. You can make sure you end the sample as it crosses the zero line by zooming in on the wave form in wave editor part of cool edit. Hope this helps, will respond again with more certainty after I test my theory.
Aug 02, 2010 01:37 am So, actually there were a couple issues with looping this sample.
1) There was silence at the beginning of the sample. That is probably the reason why no matter how you cut the end it seemed like it would fade out. Because when it was looped, right after the end, you would get the beginning silence. So I deleted the silence off the beginning so that the waveform started where it crossed the 0 point.
2) The wave is in stereo and the left and right channels cross the zero points at different points in time, and never at the same time. So, I chopped off the end of the sample to a point where one channel crosses the zero point and the other is close to the zero point. Then, if you zoom in all the way (wave editor mode, not multitrack mode), cool edit will let you manipulate the wave form by pointing and clicking and dragging the little squares with the finger. You can then drag the last square to the zero point in the channel that is not perfectly lined up.
Taking these 2 steps should get you a perfect loop. In fact I have uploaded the edited sample to my profile. Loop it and it should work perfectly. Once you know these tricks it's really simple. This took me about 3 minutes...
Aug 02, 2010 12:03 pm Damn, Coolo beat me to it. You are now Coolo the Thunder Stealer ;)
Aug 03, 2010 03:19 pm ha ha, yes do not leave your thunder unattended, for I will steal your thunder.
Aug 03, 2010 05:18 pm Do not leave thunder unattended, sounds like a song to me.
Aug 04, 2010 12:27 am hmmm, must be a metal song by thor and the war hammers???
Aug 10, 2010 07:59 am thanks guys, coolo, and all
fact is when u said that i was on another forum thanking someone for their response. i've lost count of how many forums i'm asking stuff like this!
it was indeed an issue of editing by sticking the waves at the same point you leave them at. I haven't got round to making my waves yet, But the past few days I've lost time figuring out how to get a recorder to record my pc's sounds, which i couldnt with audacity but can with something called Total Recorder.
Aug 10, 2010 10:50 pm coolo, I have a couple of questions, by wave editor mode do you mean 'waveform view'? and the zooming in aspect of your approach, by the time I reach the point the waves have become squares, there are no longer waves but linear because time has become so compressed. Surely the wave addition should be done on a bigger time frame or did you discover a way to get squares on more developed waves? Here's a screenshot of a bigger timewave with a couple of waves and another screenshot of how linear and so difficult to edit it is by the time the squares come up, if you see what I mean

Aug 11, 2010 03:36 am Well I'll be damned, I was on Soundforge right now trying to solve this and apparently, the problem is when i save a soundtrack with the same name the software just doesn't take my deletions into account, but when i click save as... into another file... it does... kinda irritating to find out this was the problem, something similarly trivial must have been happening to me with cool edit pro...
btw, i see the spots better on soundforge, more wavey, so thanks for the point about precision.
